Dynamic load resistant drilling system

A method of drilling a wellbore at an oilfield, the method comprising:

• determining a set of dynamic load input parameters for a drilling operation;
• determining a planning score corresponding to the set of dynamic load input parameters;
• commencing the drilling operation with the set of dynamic load input parameters based on the planning score;
• monitoring dynamic load information from drilling equipment during the drilling operation;
• comparing the dynamic load information to a threshold dynamic zone bounded by a plurality of boundaries to obtain a comparison, wherein at least one boundary of the plurality of boundaries varies over time during the drilling operation;
• adjusting, via a controller operating in a first control mode, one or more dynamic load parameters corresponding to the drilling operation in real-time based on the comparison;
• and
• in response to the dynamic load information falling outside the threshold dynamic zone for a threshold period of time:
• cease operating the controller in the first control mode;
• and
• regulating, via the controller operating in a second control mode, the one or more dynamic load parameters to be within one or more predetermined threshold ranges.

A method, comprising:

• determining a weight on bit value and a rotational velocity for a drilling device employed in drilling a wellbore at an oilfield;
• drilling the wellbore based on the weight on bit value and the rotational velocity;
• monitoring a dynamic load during the drilling of the wellbore;
• comparing the dynamic load to a threshold dynamic zone bounded by a plurality of boundaries to obtain a comparison, wherein at least one boundary of the plurality of boundaries varies over time during the drilling;
• adjusting, via a controller operating in a first control mode, the weight on bit value, the rotational velocity, or both based on the comparison;
• and
• in response to the dynamic load falling outside the threshold dynamic zone for a threshold period of time:
• cease operating the controller in the first control mode;
• and
• regulating, while operating the controller in a second control mode, the weight on bit value, the rotational velocity, or both to be within one or more predetermined threshold ranges.
